NWEH Our Story
NWEH formed 2008 as a not-for-profit collaboration between the
University of Manchester, in collaboration with local hospital and
General Practitioners (GPs-family doctors)
Medium sized growing company
Specialising in real world data driven clinical trials
4
Learning Objectives
1. Justify the need for a different type of clinical trial data.
2. Describe what made the Salford Lung Study so pioneering in its research
methodology.
3. Analyze patient safety monitoring challenges and how to use Real World
Studies to assess the effectiveness of new drug therapies.
4. Explain the bespoke IT infrastructure used to support the safety
monitoring and reporting during the Salford Lung Study.
5. Appraise the impact of ‘near to’ real time safety monitoring on the future of
clinical trials.

What made the Salford Lung Study so
pioneering in its research methodology?
12
Why Salford?
Greater Manchester has become one large integrated healthcare
community
All patients have a unique NHS number
Most drugs are electronically prescribed
All inclusive Salford represents a typical population
GPs have used electronic medical records since the 1990s
Sharing patient data between hospitals and GPs
Enabling linkage of patient level data between healthcare
systems
13
The first study of its kind
initiated with a pre-licence medicine
Maintains the scientific rigour of an RCT
but keeps it as near to everyday clinical practice setting as possible
Uses an integrated Health Record
that facilitates data collection without direct patient contact
An innovative collaboration
between NWEH, GSK, academia, and healthcare professionals

What made the Salford Lung Study Pioneering?
14
First prospective pragmatic randomised controlled
trial of a pre-licence medicine
Minimal exclusion criteria
Bespoke IT infrastructure to monitor subject
electronic health records remotely
Close to real-time safety reporting
Endpoints collected directly from electronic
healthcare records
Minimal intervention outside of normal care

Constant real-time data collection of all interventions and
safety monitoring
Randomisation
Aim: To compare the effectiveness and
safety of study Rx to usual care on
meaningful patient-centred outcomes in
COPD (rate of moderate/severe
exacerbations)
During the 12 month treatment period, patients can have their maintenance treatment adjusted (stepping-up,
stepping-down or switch) in both arms at the GP’s/Investigator’s discretion as would be normal clinical practice.
Salford Lung Study Design
16
To maintain the scientific rigour one associates with a
traditional randomised controlled trial
Interventional
Randomised
Control arm
But to keep it as near to everyday clinical practice as
possible
Embracing heterogeneity of the patient population
Maintaining patient experience as close to normal as possible
Collecting endpoints relevant to patients and healthcare decision makers
Comparing the study drug with ‘usual care’
What was the Intent Behind the Study
Design?
17
Intensive training of all study and site staff
Minimal study procedures and visits
Study drug accessed through community pharmacies i.e.
CVS
How did we ensure we did not interfere
with “normal” care of patients during
the study?
18
Direct extraction of study endpoints from the electronic
medical record wherever possible
Excellent and auditable IT systems with available support
staff
Fully validated system - reduced need for source data
verification
How did we ensure robust collection of
study end points?
19
Integrated electronic patient record with real-time access
ensures that the safety team are aware wherever and
whenever patient accesses healthcare
Dedicated safety team
How did we ensure robust safety
monitoring without carrying out routine
study visits?

The future
This platform enables studies to be conducted
in a broader more representative patient
population
Patients can be closely monitored without
intervention which helps maintain the ‘real
world’ methodology

enabling safety signals to be detected more
quickly than in standard clinical trials
